Because she initiated while drunk and doesn’t remember what happened. Mitsuki wasn’t drunk an had sex with a drunk Aya. Either way it’s dub con if Aya doesn’t remember due to being under the influence. It would be different if they were both drunk but they weren’t.
I don’t like this plot point either :/

Did mitsuki dub con rape Aya??? Like Aya said she didn’t remember anything???
